catalytic activity:ATP + RNA(n) = diphosphate + RNA(n+1).,function:Polymerase that creates the 3' poly(A) tail of mitochondrial transcripts. Might be responsible for the creation of some UAA stop codons which are not encoded in mtDNA.,similarity:Belongs to the DNA polymerase type-B-like family.,tissue specificity:Ubiquitous, with stronger expression in tissues with high energy requirements: heart, brain, and skeletal muscle.,
